Objective:The next big thing in hearing aids

1.5 hr

Interviews

Interviews

Hearing Aids

Oticon Streamer

24

InterviewsWhat we heard about the Streamer….

25

1.5h interviews

Anthropological Study

5 hr

26

Anthropological StudyHow we saw the Streamer used (or not)

27

Insight

Interviews: Listen to what people say

Anthropological studies: Observe what people do

How do we find out how people behave in different situations?

WEEKS

Wearable Data Logging

Log data on Streamer, which many people have with their hearing aids

29

Wearable Data Logging

But people don’t use the Streamer!

Instead, use a device like a smartphone to log data (sound environment, location, time of day…) over a period of weeks

(Not so obvious in 2009!)

Wearable Data Logging

Data-logging device:Google Nexus One

Wearable Data Logging

Data collected Sound samples Locations Key presses Subjective feedback

Extended control over the HA and the

Streamer

User program change based on location

32

Obtaining User Input

Correlate collected data with hearing aid settings to find out what settings a user prefers under given conditions.

Present two settings, A and B User states preference Analogous to visiting the

optician.

Obtaining User Input

34

Beta Test

3 hard of hearing Oticon employees Loved the A/B Test. 5 choices too many. Keep to 3 choices: A Better, B Better, No Difference. Using open domes, often could not tell difference. Use micro molds instead.

open domes micro molds (more closed fit)
